Why It Matters
Code Analyzer (formerly SFDX Scanner) is the tool Salesforce themselves use during security reviews. It bundles PMD, ESLint, RetireJS, and Salesforce’s own graph engine into a single CLI command. Run it before every deployment and you catch security vulnerabilities, hardcoded IDs, SOQL in loops, and API version issues before they reach production.
For architects setting up quality gates in CI/CD pipelines, Code Analyzer is the baseline. If your pipeline doesn’t run this, you’re shipping blind. It’s also the standard Salesforce uses for AppExchange security reviews — so if you’re building managed packages, it’s mandatory.
